A survey of sleep position of infants seen at an urban primary care center in Washington DC showed that 34.1% of infants were sleeping in the recommended supine position [17]. A subsequent study of sleep position reported by parents of black infants at a WIC clinic in Washington DC showed that 57.7% of the infants were sleeping in the supine position [13]. While there are many factors that impact parental behaviors around sleep position, the most common reasons given for supine sleeping position in this study were concern for SIDS and advice from a health care professional. These findings indicate that improved delivery of anticipatory guidance may play a role in increasing the proportion of infants sleeping on their backs.
